Yes. Hazard lights can drain the battery of your car. Any electrical device in your vehicle can become a drain if its left on without the engine running such as headlights, radios, and even door pins.

Meanwhile when your car is running, the alternator powers the electronics, so you won't have to worry about your electrical devices on your car failing on the road.
